Risk drivers like climate change are amplifying the threat of flooding, and it is imperative that countries begin preparing for what is next. According to the Marsh McLennan Flood Risk Index:
• 1 out of 3 people globally will be threatened by flooding in a 1.5 °C warming scenario, which could happen as early as 2030.
• 41% of power generation capacity, 37% of international airport seats, and 52% of international port outflows globally will be threatened by flooding in a 2°C warming scenario, which could manifest as early as 2050.
• One-third of the world’s urban areas and nearly half (45%) of the population will be threatened by flooding in a 3.5 °C warming scenario, which could happen by the end of this century. if countries fail to follow through on current pledges.
